So I just started Raiding. We were doing Magmaw, the slimey worm, and I noticed that there were no DOT effects on him at any time. I assumed that this was due to some mechanic in the fight I was unaware of. Then I noticed that none of the bosses had DOT effects on them.
Is this a new thing? We did not have any Warlocks in the group, but did have a shadow priest.
